kandi X-RAY | python3 Summary
This is a concise Python 3 programming tutorial for people who think that reading is boring. I try to show everything with simple code examples; there are no long and complicated explanations with fancy words. If you have never programmed before click here to find out what programming is like and get started. This tutorial is aimed at people with no programming experience at all or very little programming experience. If you have programmed a lot in the past using some other language you may want to read the official tutorial instead. You can use Python 3.3 or any newer Python with this tutorial. Don't use Python 2. If you write a Python 2 program now someone will need to convert it to Python 3 later, so it's best to just write Python 3 to begin with. Python 3 code will work just fine in Python 4, so you don't need to worry about that. Python 2 also has horrible Unicode problems, so it's difficult to write Python 2 code that works correctly with non-English characters (like π and ).

I have a Python script that I'm working on where I would like to iterate through a list of ID values at the end of a URL.
This is my script so far where I would like to replace the 555 portion of the url with a list of ID values such that the script would do a POST for each of them. How can I accomplish that?

QUESTION
I'm running boto with python3 and I'm running an ansible playbook to setup some ec2 instances.
Everything is fine, creating instances, security groups, key pairs, everything in eu-west-2
.
When the task for Elastic IPs runs it fails with this message:
Region eu-west-2 does not seem to be available for aws module boto.ec2. If the region definitely exists, you may need to upgrade boto or extend with endpoints_path
I'm running ansible with -e ansible_python_interpreter="/usr/bin/python3"
.
I have latest boto installed.
ANSWER
Answered 2021-Mar-03 at 11:06I resorted to using the community module for elastic ip.
So community.aws.ec2_eip
instead of ec2_eip

QUESTION
I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:
I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:
...ANSWER
Answered 2021-Jun-15 at 06:17Pythons multiprocessing package is limited to shared memory parallelization. It spawns new processes that all have access to the main memory of a single machine.
You cannot simply scale out such a software onto multiple nodes. As the different machines do not have a shared memory that they can access.
To run your program on multiple nodes at once, you should have a look into MPI (Message Passing Interface). There is also a python package for that.
Depending on your task, it may also be suitable to run the program 4 times (so one job per node) and have it work on a subset of the data. It is often the simpler approach, but not always possible.

QUESTION
I am modeling a Time-constrained CVRP. The problem is to minimize the total travel time (not including the package dropping time) subject to vehicle (delivery) capacity and total time spent (per vehicle) constraints. The package dropping time refers to an additional time to be spent at each node, and the total time spent equals to the travel time plus this additional time. I have the below model that works for a single vehicle-type case. I would like to introduce two-vehicle type concept in there, meaning that I have a set of V1
type vehicles and another set of V2
type vehicles. The only difference of the vehicle-types is the per time cost of travel. Let x
denote the per time unit cost of travel by V1
, and y
denote the per time unit travel cost of V2
. How can I design the model so that it incorporates this additional aspect?
ANSWER
Answered 2021-Jun-13 at 13:34Simply register two transits callbacks (i.e. one per vehicle type)
Then use the overload of AddDimension() to pass an array of registered transit callback index.

Install python3
You can use python3 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
